Anthurium plant named `Cleopatra`

ABSTRACT

A distinct cultivar of Anthurium plant anmed `Cleopatra`, characterized by its upright, outwardly arching and very freely clumping growth habit; moderate to rapid growth rate; large green leaves that are ovate in shape; numerous inflorescenes that are positioned upright and just above the foliage on strong and erect scapes; durable white spathes with pink spadices; year-round continuous flowering; and good post-production longevity.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum, and hereinafter referred to by the cultivar name `Cleopatra`.

The new Anthurium is a product of a planned breeding program conducted by the Inventor in Schipluiden, The Netherlands. The objective of the program is to create new Anthurium cultivars that have freely clumping growth habit, strong plant growth, attractive spathe color, numerous inflorescences and leaves, and good post-production longevity.

The new Anthurium ori ginated from a self-pollination by the Inventor on Jul. 15, 1993 of the Inventor's proprietary Anthurium andreanum selection code Number 93-18. The cultivar `Cleopatra` was discovered and selected by the Inventor as a plant within the progency of the stated cross in a controlled environment in Schipluiden, The Netherlands in the October, 1995. Asexual propagation of the new cultivar by tissue culture in a laboratory in Belgium has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

The new Anthurium has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of the cultivar `Cleopatra`. These characteristics in combination distinguish `Cleopatra` as a new and distinct cultivar:

1. Upright, outwardly arching and very freely clumping growth habit.

2. Moderate to rapid growth rate.

3. Large dark leaves that are ovate in shape.

4. Numerous inflorescences that are positioned upright and just above the foliage on strong and erect scapes.

5. Durable white spathes with pink spadices.

6. Year-round continuous flowering.

7. Good post-production longevity.

The new Anthurium can be compared to the parent, the Inventor's proprietary selection code No. 93-18. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of selection code Number 93-18 in the following characteristics:

1. Plants of the new Anthurium have smaller and more durable leaves than plants of the selection code Number 93-18.

2. Plants of the new Anthurium and the selection code No. 93- 18 differs in spathe and spadix colors.

3. Plants of the new Anthurium have flatter and more cordate spathes than plants of the selection code Number 93-18.

The new Anthurium can be compared to the nonpatented Anthurium cultivar `Desiree`. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of the cultivar `Desiree` in the following characteristics:

1. Plants of the new Anthurium are more compact than plants of the cultivar `Desiree`.

2. Plants of the new Anthurium have darker green, smaller and stiffer leaves than plants of the cultivar `Desiree`.

3. Plants of the new Anthurium have smaller and stiffer spathes than plants of the cultivar `Desiree`.

4. Plants of the new Anthurium and the cultivar `Desiree` differ in spathe and spadix colors.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Anthurium, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph on the first sheet comprises a top perspective view of a typical potted plant of the cultivar `Cleopatra`.

The photograph on the second sheet comprises a close-up view of a typical spathes and spadices of the cultivar `Cleopatra`. Leaf, spathe and spadix colors in the photographs may appear different from the actual colors due to light reflectance.
